Abstract
Изобретение относитс к металлообработке и может быть использовано дл закреплени деталей. Цель изобретени - повышение точности закреплени посредством равномерного распределени усилий закреплени . В корпусе 1 установлена т га 2. а на поверхности корпуса 1 установлена цанга 3, прижата к конусу корпуса 1 дву- плечим рычагом 4, взаимодействующим с т гой 2 посредством подпружиненного фиксатора 5 и опорного винта 6. Базовые поверхности рычага 4 контактирующие с цангой 3, фиксатором 5 и опорным винтом 6, выполнены сферическими, что позвол ет избежать в процессе работы перекоса цанги 3. Деталь устанавливаетс на поверхность цанги 3 и досылаетс до торца Б оправки. При движении т ги 2 рычаг 4 передвигает цангу 3 и производит закрепление детали, 1 3.п. ф-лы, 2 ил.The invention relates to metalworking and can be used to secure parts. The purpose of the invention is to improve the fixing accuracy by uniformly distributing the fixing forces. In case 1, a ha 2 is installed. And on the surface of case 1, a collet 3 is installed, pressed against the cone of case 1 by a double-arm lever 4, which interacts with the thrust 2 by means of a spring-loaded clamp 5 and a support screw 6. The latch 5 and the support screw 6 are made spherical, which makes it possible to avoid the collet 3 from tilting during operation. The part is placed on the surface of the collet 3 and is extended to the end face B of the mandrel. During the movement of gi 2, the lever 4 moves the collet 3 and fixes the part, 1 3.p. f-ly, 2 ill.
